historical_data_lookback = (no_of_candles // 360) + 1
today2 = datetime.now().strftime(“%Y-%m-%d”)
yesterday2 = (datetime.now() - timedelta(days=4 + historical_data_lookback)).strftime(“%Y-%m-%d”)
print(f"yesterday={yesterday2},today={today2}")

            url2 = f'https://api.upstox.com/v2/historical-candle/{symbol}/1minute/{today2}/{yesterday2}'
            headers2 = {'Accept': 'application/json'}
            response2 = requests.get(url2, headers=headers2)
            response2.raise_for_status()

Hi @Vibhuvan_Krishna, Could you please share the instrument key for which the historical data is missing? I’m able to retrieve the correct candle data for the last 7 days using the cURL request below.

curl --location 'https://api.upstox.com/v2/historical-candle/NSE_EQ%7CINE848E01016/1minute/2025-04-07/2025-04-01' \
--header 'Accept: application/json'

Please make sure to account for holidays and weekends in your data. Also, note that intraday data is not available through the Historical API.

Thanks

Hi @Vibhuvan_Krishna, please try using the following URL: https://api.upstox.com/v2/historical-candle/NSE_FO|43826/1minute/2025-04-07/2025-04-02. It should return the data you need for the period from 2nd to 7th April.

Thanks!

@Vibhuvan_Krishna It appears that no trades occurred on the 3rd and 4th of April for the given instrument thats why no data.

@Vibhuvan_Krishna Yes, the data is consistent across all platforms.
